I have AVG antivirus and nope I have not tried the graphic card in a different pc because is water attached to the other 3 since they are in the same loop. I have thought about doing a fresh windows install but I wanted to try everything else before
 
I tan the antivirus yesterday 4 times and everything is clear. Also, the issue did started after a few hours of me downloading NVidia inspector from one side and 2 391kb documents from another for fsx.
 
Any idea of another software that I could run to try to eliminate such "virus" or your suggestion is to  call it quits and installed a fresh copy of windows again?
 
 
Ps. Thanks for answering  pal.

Also download Malwarebytes free and scan 
 

Look in task manager to see if you have any Java Programs active.
I've run across the odd java app that pegs the graphics card if it can.
If it is Java, it's either badly coded or makes some kind of improper call/usage of a library file that gobbles up GPU cycles.
 
It could also be a bitcoin virus or some other virus that uses the power in gpu's.
What happens if you connect your monitor to another card and disable the primary card ?
 
If it's not that, run msconfig with selective startup and see if it's a program in startup or services that's using your card.
 
If you've got Symantec Ghost just recover from your last image or Possibly try a "Windows Last Restore Point" from Safe Boot, if you have that active.  If not, you may have to reinstall windows. 
 
If you do re-install, consider getting an "Image" program to save and recover your known good working install of windows so that if something goes wrong again, you can restore your system in less than 30 mins without re-installing and setting up all your software again.
 
If you've got steam or tons of software installed and setup, consider multi-partitioning your drive(s) so that you can restore windows with the least effort and time required.
 
Good Luck,
Pete

Sounds like you're infected with a bitcoin miner. Download Malwarebytes, update the definitions file and run a full scan to see it you are infected or not. http://www.malwarebytes.org/mwb-download/
 
Perform a clean boot of windows if malwarebytes doesn't find anything. 
 
Other info...
 
BSOD 0x116 & 0x117 causes:
 
#1 Bad video driver or corrupt video driver.
#2 Defective video card.
#3 Insufficient power to GPU or defective PSU.

You could also try this...
 
To locate which process on your computer is causing the high load do the following...
 
- Download process explorer and run it.
- Select view (top left), select columns, select process gpu, check mark gpu usage (this will create a column on the main screen called "GPU", you will be able to monitor what process is using your GPU the most when idle.) 

Here is an image of the usage.
 
Please bare in mind this is not under SLI since if cannot activated without all gpus going to 521543135% of usage and crashing.

I believe I got both issues at the same time. (death graphic card and virus)
 
Check these numbers at idle and without gpu 2 being in the picture
 
   

Fresh Install did not solved much so I just replaced the gpu with the 4th one that I had left from my previous 4 SLI  config and "problem solved". Pretty sure still have a virus of some sort but gpu usage is back to normal. I  will do a fresh install of windows once I change some parts that are long overdue.
 
 
Anyway, GPU2 went bad after 6 years for no reason.
 
Thank you all for taking the time to help me out.
